How to Track Car Maintenance Without Forgetting What's Due

Car maintenance has deadlines. MOTs, services, insurance, tax. Some are legal requirements. All cost more if you forget them.

Here's how to track everything without spreadsheet overload.

What Actually Needs Tracking

Not every car-related task. Just the scheduled and required ones.

Legal requirements:

• MOT (annual test)
• Car tax (annual or 6-monthly)
• Car insurance (annual)

Recommended maintenance:

• Annual service
• Oil changes (if not covered by service)
• Tyre rotation/replacement
• Brake checks
• Battery checks

Mileage-based:

• Major service intervals
• Cambelt replacement
• Brake fluid change

The Two-Part System

Part 1: Calendar for date-based tasks Part 2: Mileage tracker for mileage-based tasks

Both necessary. Different triggers.

Part 1: Date-Based Tracking

Calendar events with smart reminders.

MOT Test

Set three calendar events:

Event 1: 60 days before expiry

• Title: "PREPARE: MOT due in 2 months"
• Action: Research garages, get quotes
• Time to shop around

Event 2: 30 days before expiry

• Title: "BOOK: MOT appointment"
• Action: Book test at chosen garage
• Still legal to drive

Event 3: 7 days before expiry

• Title: "MOT test booked for [date]"
• Action: Verify appointment, prepare car
• Final reminder

Event 4: Expiry date

• Title: "DEADLINE: MOT expires today"
• If you see this, something went wrong
• Don't drive after this date without MOT

After test:

• Update calendar with next year's date
• Note test centre if you liked them
• Save certificate digitally

Car Insurance

Set three calendar events:

Event 1: 45 days before renewal

• Title: "COMPARE: Car insurance renewal approaching"
• Action: Get comparison quotes
• Time to find better deals

Event 2: 21 days before renewal

• Title: "DECIDE: Car insurance"
• Action: Choose provider (switch or stay)
• Still time to switch

Event 3: 7 days before renewal

• Title: "CONFIRM: Car insurance renews [date]"
• Action: Verify renewal or switch is active
• Final check

After renewal:

• Update calendar for next year
• Save policy documents
• Note premium for comparison next year

If you automate payments, make sure you’re reviewing them properly — this guide to automating bill payments explains how to do it without losing oversight.

Car Tax

Set two calendar events:

Event 1: 14 days before expiry

• Title: "RENEW: Car tax due"
• Action: Renew online (takes 5 minutes)
• Must have valid MOT

Event 2: Expiry date

• Title: "DEADLINE: Car tax expires"
• Illegal to drive without tax
• Penalties may apply

After renewal:

• Update calendar (1 year or 6 months depending)
• No paper disk needed anymore
• Police check electronically

Annual Service

Set two calendar events:

Event 1: 30 days before due

• Title: "BOOK: Annual service due"
• Action: Book service appointment
• Based on last service date or mileage

Event 2: Service due date

• Title: "Service due"
• Reminder if you haven't booked

After service:

• Update calendar for next year
• Save service receipt
• Note any recommendations
• Update mileage tracker

If you want a broader structure for handling recurring tasks beyond car admin, this minimal annual task system explains the full framework.

Part 2: Mileage-Based Tracking

Simple spreadsheet with one row per service type.

Spreadsheet Structure

Example entries:

Using the Mileage Tracker

Check monthly:

• Note current mileage
• Compare against "Next Due" column
• If within 1,000 miles of service: Book it

After each service:

• Update "Last Done Mileage"
• Calculate next due (Last + Interval)
• Update "Last Done Date"
• Add notes about service

Common Service Intervals

Note: Service intervals vary by manufacturer and driving conditions. Always check your vehicle's manual for specific guidance. The following are typical ranges:

Typically every 5,000-10,000 miles:

• Oil change (varies by oil type)
• Basic health check

Typically every 10,000-12,000 miles:

• Minor service (oil, filters, checks)

Typically every 20,000-24,000 miles:

• Major service (includes minor service plus more)

Typically every 60,000-100,000 miles:

• Cambelt/timing chain check/replacement
• Transmission fluid
• Coolant flush
• Major component inspections

Check your car's manual for specific intervals.

The Service Record Book

Keep physical or digital record of all work done.

What to Record

For every service/repair:

• Date
• Mileage
• Work performed
• Parts replaced
• Cost
• Garage name
• Any recommendations

Why Keep Records

Resale value:

• Full service history increases value
• Proves car is maintained
• Buyers want to see this

Warranty claims:

• May require proof of maintenance
• Service history shows regular care

Pattern spotting:

• Recurring issues identified
• Helps diagnose problems

Budgeting:

• See what you actually spend
• Plan for upcoming costs

Storage Options

Physical book:

• Many cars come with service book
• Garage stamps it
• Keep in car (or safe at home)

Digital folder:

• Scan all receipts
• Name: YYYY-MM-DD_Service_Mileage
• Example: 2024-03-08_AnnualService_45000
• Cloud backup

A simple digital filing system makes storing service records painless.

Both:

• Physical as primary (for resale)
• Digital as backup (in case book lost)

If you’re unsure how long to keep vehicle paperwork, see this guide on document retention in the UK.

Tyre Management

Separate from general maintenance because tires need specific tracking.

What to Track

Tyre information:

• Size (from sidewall)
• Brand/model currently fitted
• Purchase date
• Mileage when fitted

Condition tracking:

• Tread depth (check monthly)
• Pressure (check monthly)
• Visible damage
• Rotation schedule (every 6,000-8,000 miles)

Tread Depth Monitoring

Legal minimum: 1.6mm across central 3/4 of tyre

Replace when: 3mm (for safety margin)

Check with:

• 20p coin (outer band should be visible if tread is deep enough)
• Tread depth gauge (£5, more accurate)

Monthly check:

• Insert 20p into tread
• If outer band visible: Tread is good
• If not visible: Tread is low, measure properly

Record in tracker:

• Date checked
• Depth measurement (if using gauge)
• Tires checked (note if any lower than others)

Tyre Pressure

Check monthly:

• Recommended pressure on sticker (driver's door frame)
• Check when cold (not after driving)
• Include spare tyre

Note in tracker:

• Date checked
• Any pressure adjustments made
• If repeatedly losing pressure: Note for garage

Warning Light Response System

When dashboard lights appear, you need system to track and respond.

When Warning Light Appears

Immediate actions:

1. Note what light appeared

2. Check manual for meaning

3. Assess severity:

   • Red = Stop immediately
   • Amber = Get checked soon
   • Yellow = Monitor and book service

4. Add to car maintenance tracker

5. Book garage if needed

Tracking Intermittent Issues

For lights that come and go:

• Note date/time each occurrence
• Note conditions (weather, speed, etc.)
• Pattern helps diagnosis
• Show garage your notes

The Monthly Car Check Routine

10 minutes monthly prevents forgotten maintenance.

First Sunday of each month:

Check dashboard reminders:

• Mileage to next service
• Any warning lights

Physical checks (5 minutes):

• Tyre pressure (all including spare)
• Tread depth (20p test)
• Windscreen washer fluid
• Obvious leaks under car

Update trackers (5 minutes):

• Record mileage
• Check if anything due soon
• Book appointments if needed

Review calendar:

• Any MOT/insurance/tax coming up
• Appointments booked

Done. Back to life.

Preparing for MOT

Month before test, do pre-MOT check to avoid failures.

Common MOT Failures (Check These)

Lights:

• All lights work (headlights, brake, indicators, reverse)
• No blown bulbs
• Replace before test

Tires:

• Tread depth above 1.6mm
• No visible damage
• Correct pressure

Brakes:

• No squealing or grinding
• Brake fluid at correct level
• Handbrake works

Windscreen:

• No chips/cracks in driver's view (larger than 10mm)
• Wipers work and don't streak

Horn:

• Works

Seat belts:

• All present and working
• No fraying

Fix obvious issues before test. Saves re-test fee.

Dealing with Unexpected Repairs

Not all maintenance is planned.

When Something Breaks

Immediate:

1. Assess if car is safe to drive
2. If not safe: Don't drive, call recovery
3. If safe: Book garage appointment

Before garage:

• Note symptoms clearly
• When did it start
• Does it happen always or sometimes
• Recent changes or work

At garage:

• Describe symptoms clearly
• Ask for written quote before work
• Ask about warranty on repair
• Get itemized receipt

After repair:

• Add to service record
• Update mileage tracker if relevant
• Note garage quality (use again or avoid)

Emergency Fund

Cars break. Budget for it.

Typical annual costs:

• MOT: £35-55
• Service: £100-400
• Insurance: £400-1,500
• Tax: £20-700
• Tires (every 2-3 years): £200-600
• Unexpected repairs: £200-500

Total: £1,000-3,500/year depending on car age and type.

Set aside monthly. Prevents panic when bill arrives.

Keeping visibility over recurring expenses — including insurance and subscriptions — helps prevent surprises (see this guide on tracking subscriptions).

Digital vs. Physical Tracking

Recommendation: Both.

Calendar (digital):

• Date-based reminders
• Automatic recurring events
• Alerts on phone

Service book (physical):

• Proves maintenance for resale
• Standard format garages understand
• Stays with car

Mileage tracker (digital):

• Easy to update
• Quick to reference
• Backed up automatically

Receipts (both):

• Physical in service book
• Digital scans as backup

When to DIY vs. Garage

Some maintenance you can do. Some needs professionals.

Safe to DIY:

If competent:

• Washer fluid top-up
• Basic bulb replacement
• Air filter replacement
• Battery terminal cleaning
• Tyre pressure checking

Learn once, do forever.

Always Use Garage:

For safety and legality:

• MOT (must be authorised centre)
• Anything brake-related
• Anything safety-critical
• Anything needing specialist tools
• Anything affecting warranty

Don't save £30 on repairs and create £3,000 problem.

The New Car Setup

When you get different car, set up tracking from day one.

Day 1:

1. Find service book (or create digital one)
2. Note current mileage
3. Find MOT expiry date (check online at gov.uk/check-mot-history)
4. Find insurance expiry
5. Find tax expiry

Week 1: 6. Set up all calendar reminders 7. Create mileage tracker with service intervals 8. Read manual for service schedule 9. Take photos of tyre size/specs

Month 1: 10. First monthly check routine 11. Learn where everything is (fluid caps, spare tyre, etc.) 12. Find good local garage

Start organised, stay organised.

Common Mistakes to Avoid

Relying on Memory

You won't remember MOT is due in 3 months. Calendar will.

Waiting Until Due Date

Everything is more expensive and stressful last-minute.

Not Keeping Records

Reduces resale value. Harder to track patterns. Wastes money.

Ignoring Warning Lights

Small problems become expensive problems. Check immediately.

Skipping Monthly Checks

5-10 minutes monthly prevents expensive failures.
